DIY easy to implement Google reCAPTCHA replacement...
Bots are something every website deals with as long as it is online. It's up to you to prevent your database from being filled with garbage entries by allowing only humans to interact and submit data on your online forms.
The best form builder module in DNN allows you to create pretty much anything you can think of; of course, in case it doesn't already have it as a default feature.
Today's tutorial shows you how to create, with Action Form, your custom CAPTCHA for situations when your users report that they can not submit the forms because the Google reCAPTCHA is not working; reports say that the recaptcha field doesn't work on some mobile browsers (like Samsung browser).
To go around this you can:
- either ask your users to use a newer browser (like Chrome - of course google's captcha works on google's browser :) ) which some time is impossible to be achieved especially on older devices or for less experienced users
- or take the matter in your own hands and come up with an in-house captcha verification as an alternative to the reCAPTCHA field
This video show you how easy is to implement a simple math captcha verification which should offer a 100% browser compatibility regardless of the device your users use.
